great video i had a feeling when it was 2 different fuses where you were going you explain things in a way that makes it easy to understand great experiment 😁

Pretty cool stuff Carter! Even if I never see a Nissan Rogue in my shop with this problem, the fundamentals and thought process that you teach are so valuable. I love that you prove out every diagnosis. You truly are an "Auto Nerd"! Thanks again for educating.

My goal is to explain in a way that the fundamentals will apply to all makes and models. It just so happens Nissan is my platform. Thank you for the positive feedback! And yes I am an "Auto Nerd" !🤣

Always good when you weigh in with a new video. 3 things i thought were curious. 1- In the Rogue capture you pointed out what you called a step down on power side just after capacitor discharge. Looked like a wider pulse all by itself. That does not appear to be there on 20 Altima or 19 Altima you did a few months ago. Wonder why? 2- Diagram showed what it called was a high pressure fuel pump relay. Assume that is actually for pressure regulator? 3- Curious if different fuse size was related to possibility that injectors were different part# with different characteristics. Don't know why Nissan would do that but manufacturers do weird things. Thanks Mike, great video.

Great question, I can only speculate but on question 1, its possible the Altima was on some sort of default fuel strategy, due to me messing with it so much. Question 2 is yes its the fuel inlet solenoid on the high pressure pump. Question 3 I have to agree, anything is possible when it comes to the flow characteristics of these injectors. Also the Rouge is a 2.0L engine and the Altima is a 2.5L that may also play a part . And yes I agree 100% manufacturers do some crazy stuff. Thats what keeps me up late a night!

2.0 litre in the Rogue, yeah that probably says alot in regards to fuse size. Watched that video again and it finally hit me that the Rogue injectors were indeed drawing less current than the Altima you compared it to. I guess thats why they thought it only needed a 10 amp fuse. Thats why the engineers get paid the big bucks.

Wouldn't this have been so much easier to troubleshoot had there been a Pxxxx "loss of voltage to injector power supply 1/2"? I'm surprised your experiment of pulling fuses didn't set any DTC's. Secondly - if the relay is hard to get to being behind the fender liner, as a future quick test, you can pull the fuses and install amp clamps on the two individual fuses. That can give quick direction at the beginning of a diagnosis. I imagine you'd see all injectors current ramps for their initial slam open and then for their pulse-width hold opens.

Yea sometimes I wonder about code set criteria, an evap small leak or catalyst code will set instantly but an obvious voltage drop issue won't??? Crazy stuff.

Great explanation. So did you change the relay or the whole fuse box ?

The harness had been replaced do to collision damage. The old relay was swapped into the new harness?? We simply installed a new relay.
